INTRODUCTION: This study was conducted to survey current practices in the treatment of haemorrhoids (Hs), prevalence of complications associated with injection sclerotherapy (IS) and attitudes to its use to treat anterior Hs. METHODS: Postal questionnaires were sent to 92 consultant surgeons in the South East Thames Region. They were returned anonymously. RESULTS: Seventy questionnaires were returned (76% response rate) and 61 questionnaires were used in the data analysis; 18 from coloproctologists and 43 from non-coloproctologists who treated Hs. First degree Hs were mostly treated with IS alone (76%). Second degree Hs were treated with rubber band ligation (RBL) alone (36%) or a combination of IS and RBL (36%). Third degree Hs were mostly treated with haemorrhoidectomy (76%). Nineteen surgeons (31%) reported complications using IS; 82% of these were urological. Nine surgeons (15%) did not use IS to treat anterior Hs and 10 (16%) advised their trainees not to inject anteriorly. CONCLUSIONS: IS is a common treatment of Hs. Nearly one-third of consultants reported complications, the majority of which were urological and likely to be secondary to IS of anterior Hs. It may be safer to avoid IS of anterior haemorrhoids.
